针对混凝土小型空心砌块(简称砌块)热工性能较差的缺陷,利用泡沫混凝土填充砌块孔洞来提高砌块平均热阻,成为一种自保温砌块。本文研究泡沫混凝土的抗压强度以及绝干密度与导热系数的相关性,确定绝干密度为(240±20)kg/m3的泡沫混凝土适宜作为自保温砌块填充保温材料,探讨泡沫混凝土对砌块热工性能的改进效果。 In view of the shortcomings of poor thermal performance of concrete small hollow block (referred to as block), the use of foam concrete to fill block holes to improve the average block resistance, a self-thermal block. In this paper, the compressive strength of foam concrete and the correlation between absolute dry density and thermal conductivity were studied. It was found that the foam concrete with a dry density of (240 ± 20) kg / m3 was suitable as a self-insulation block filled thermal insulation material. Block thermal performance improvement effect.
